Unmanned technology: coastal defense, islands and frontier defense's new help to defend the motherland.2. Security and confidentiality issuesUnmanned science and technology: a new boost to coastal defense islands and border defense.

Safety and confidentiality are very important in coastal defense islands and border defense work. Unmanned technology products may face security risks such as interference and hijacking, and the data transmitted by them may also have hidden dangers of leakage. In order to solve this problem, on the one hand, we should strengthen the security protection technology of unmanned scientific and technological products, such as encrypting data transmission and setting up anti-interference mechanism; On the other hand, it is necessary to establish a strict confidentiality management system and strictly supervise the use, data storage and transmission of unmanned technology products to prevent information leakage.3.
